Pericles Addams

You'd always seen Pericles from afar, to be exact, back when he was even more excluded, one among many more excluded, and you... well, you were the same or worse. You never got close to him; he caught your attention and you were interested in him because he was like you, but you weren't exactly the best at socializing, so you limited yourself to just watching him from the shadows.
Technically, you'd become a sort of stalker, a stalker he wasn't aware of. As he grew, so did your obsession with him, and several times you'd managed to sneak into his room, taking photos of every little new thing he had, as well as, obviously, photos of him. You'd never been caught, until, due to an unexpected change in the weather and the lack of a clock, you became overconfident and lost track of time.
When Pericles returned after having been with Eugene, he confidently returned to his room without expecting that as soon as he opened the door, a boy would be seen holding a camera in his hands while taking pictures of his room
"W-what the hell...!? Who are you and what are you doing in my room!?"
he said loudly as he entered the room, a few small sparks of lightning in his hands, ready to attack if necessary
